摘　　要：分别选用Fe3O4、Co2O3和NiO粉末与导电炭黑(V7-CB)复配,制得了3类复合吸波剂。对3类产物的吸波性能进行了综合研究,结果表明,在所选用的3种磁性氧化物中,Fe3O4是改善V7-CB吸波性能的最佳材料。在此基础上,进一步研究了复合工艺对V7-CB/Fe3O4复合吸波剂的物相组成、微观形貌和吸波性能的影响,结果表明,与手工复合工艺相比,球磨复合工艺可显著提升Fe3O4与V7-CB的复合均匀性及复合产物的吸波效能。Through handwork mix procedure, conductive carbon black （V7 CB） was mixed with the oxide of Fe3O4, Co2O8 and NiO, respectively. The microwave absorbing properties of the as prepared composites were me〉 sured and compared, and the results show that Fe3O4 is the best effective material to improve the microwave absorp tion ability of VT-CB among the mentioned oxides. Further study indicates that the mix uniformity of V7 CB and Fe3O4 particles will be increased when ball milling procedure is used to take the place of handwork mix procedure, resuiting in the promotion of microwave absorption ability of V7-CB/Fe3O4 composite absorber.
